Who is performing as special guests on the result shows this week. The only one I know off is Alesha who I think is performing on Wednesday and last years winner's Collabro will probably perform

According to wikipedia the guest performers are

Monday - *Ricky Martin*– "Mr. Put It Down"

Tuesday - Jack Pack

Wednesday - *Alesha Dixon*– "The Way We Are"

Thursday - Olly Murs - Beautiful to Me

Friday - Collabro

Final - Sunday - Andrea Bocelli*and Michael Flatley's*Lord of the Dance

Dont know if this is correct or not if it is, it is quite weak
